Ok Guy's I have a Y7 bottom end with a Z6 Head (running good)
I swapped the Z6 cam and cam gear and put a Y8 Cam and Cam gear in.
Now for somereason it is only running on cylinders 2 and 4 all of the plugs are getting spark just put new plugs in and the it timing is set right.
On a p2p ECU it throws a 9 which is cylinder sensor

Anyone got and sugestions?

 

t belt on correctly? reset base timing? if you did was it within spec? what did you do if it wasnt?

 

hmmm, try getting another z6 cam and cam gear and put it in and see what happens if the same problem occurs then its not the y8 cam and cam gear if the problem goes away stay with the z6 cam and cam gear or get after market ones.

 

are the 2 cams that much diff? to cause a problem like this? i proly gonna put the z6 cam back in tonight and yea the timing belt is on right and it is in time
